VB.Net中的SQL语句错误

Question

This is the SQL statement which I taken from debug mode in VB.Net.

SELECT  dt_Date as 'Date', 
        s_Time as 'Time', 
        s_For as 'For', 
        s_Categ as 'Category', 
        s_Count as 'Count', 
        s_Remarks as 'Remarks' 
FROM Entry 
WHERE (s_ENo = '22' and dt_date BETWEEN '06-05-16' And '27-05-16')

I am not sure what's wrong with the above statement since everything seems to be fine to my eyes.

Description of the Error Message

Additional information: Conversion failed when converting date and/or time from character string.

Any suggestions how to solve this riddle?

Answer 1

Instead if string literals, use strongly-typed parameters. In addition to avoiding data type conversion issues on the SQL Server side, parameters:

• Avoid the need to format date/time string literals in a particular way
• Improve performance by providing execution plan resue
• Prevent SQL injection (barring dynamic SQL on the server side)

Answer 2

If you are using MS-SQL server than use following instructions.

The basic solution is that you have to provide date into either mm/DD/YYYY format or in YYYY-MM-DD date format into ms-sql query.

So, before passing date to query convert your date into either mm/DD/YYYY format or in YYYY-MM-DD format.

Answer 3

您必须将日期字符串格式设置为YYYYMMDD，或者如果您知道服务器日期格式，则与服务器格式相同
